driver mcbsp0(ad535) and mcbsp1

Started by feu_andi June 30, 2003
Hi There
I'm about to write DSP/Bios drivers. My first driver is the DMA
interrupt-driven low-level streaming device driver (example comes with
spra802)
My second driver should be similar, but communicate not over the ad535
codec. Instead of that only write and receive data to and from the
MCBSP1.
Both drivers should work with EDMA.

is it possible easily to bind both drivers in a project and let them
communicate?

I simply commented out the things necessary for ad535 and changed the
names for mcbsp0 to mcbsp1. I configured the mcbsp (hopefully right).
but the EDMA interrupt never occurred.

best regards
andi



Andi,

Since it sounds like you are just getting started, I'd recommend updating to
the newer DSP/BIOS device driver model (LIO has been updated and improved to
IOM model).

Checkout the Device Driver Developer's kit or if you are just interested in
writing a driver for DSK6711 then spra850.pdf.

DDK is available at:
